[0016] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0017] Referring to Figure 1 As shown in Figure 2 A steel-making furnace feeding device, comprising a support column and a support rod 1, the support rod 1 is vertically fixed on a support base 2, the support rod 1 is transversely connected with a telescopic rod 11, the telescopic rod 11 is a hydraulic rod, a hydraulic cylinder 12 is arranged below the telescopic rod 11 to control the extension length of the telescopic rod 11. One end of the telescopic rod 11 is provided with a first fixed pulley 7 and a second fixed pulley 8, the first fixed pulley 7 and the second fixed pulley 8 are respectively passed through a second rope 5 and a first rope 4, the second rope 5 and the first rope 4 are connected to a placing basket 3 below, one end of the first rope 4 is connected to a first electric winding roller 6, and the other end of the second rope 5 is connected to a second electric winding roller 10.
[0018] The lower end of the first rope 4 is connected to one end of the placing basket 3, and the lower end of the first rope 4 is arranged at the center of the placing basket 3. When it is needed to pour, the first electric winding roller 6 controls the upward pulling of the first rope 4, and the second rope 5 is stationary, so as to tilt the placing basket 3, and the raw materials in the placing basket 3 enter the steelmaking furnace.
